VIII

VIII cervical and I and II thoracic segments in Dejerine-Klumpke paralysis. The worm-like muscles. Next, the paralysis also affects the flexors of the hand, located on the anterior surface of the forearm. Sensory disturbances correspond to the general schemes of radicular distribution of sensitivity: anesthesia affects on the hand the area innervated by the ulnar nerve, partially also the area innervated by the median nerve, the inner surface of the forearm and the inner surface of the arm. In the eye area on the corresponding side, the Horner symptom complex is noted: narrowing of the pupil and eye fissure and enophthalmus (see). The course of the disease, prognosis, and therapy are completely determined by the etiology of the disease (trauma, syphilis, tumor, etc.). The topological diagnosis in typical cases does not present particular difficulties, the recognition of the cause of the lesion proceeds according to the usual principles. X-ray and Wassermann reaction (RW) are of great importance here for differential diagnosis.
